Product Description
When regular shampoos aren't cutting it and you need a heavy-duty cleanse, K18 Peptide Prep Detox Shampoo is the way to go.
What makes this shampoo so great? In addition to activated charcoal for absorbing oils and dirt and salicylic acid for clearing sebum buildup, this non-stripping but ultra-cleansing shampoo contains the K18PEPTIDE™to reduce protein loss and leave your hair softer and healthier than ever before.
Work up this clean, citrus-scented shampoo into a lather and let it balance your hair and scalp's equilibrium, thanks to its pH of 3.8-4.2 (the ideal pH for hair). In just one wash, it removes 99% of product build up and 95% of sebum.
This shampoo also functions as prep for your other products, clearing your hair's slate to make masks and chemical treatments work better and hair color apply more vibrantly.
